Acadia National Park Managers’ Report
A citizen science early-detection summary
Welcome to the weekly early detection report of observations submitted by iNaturalist and eBird users. These are all observations submitted over the past week for species that Acadia National Park managers and partners have identified as being of conservation interest. These data for this report comes from two of the largest open source citizen science projects: iNaturalist and eBird. The records included in this report include both casual and research grade observations, so erroneous identifications are possible. Users should double check the identification of species to ensure they are correct.
